PLEX server no longer launches after software update

HELP!! Running PLEX App through WD My Cloud Home NAS… did mandatory update for WD and then PMs stopped working… completely reconfigured PLEX and then PLEX required update as well and now the PMS begins to launch and then just stops. The PLEX desktop app launches but without the PMS it doesn’t really “work”… I’ve rebooted both my system and the WD NAS but that did not fix the issue… I’ve checked everywhere for solutions and no joy :hushed:
Any assistance would be so very much appreciated

Same issue, updated Plex, also updated to the latest MacOS 10.15.5 beta, and PMS dies instantly and won’t run.
